Abstract :
A nonlinear paraxial wave equation (NPWE) is derived in this work. It describes the beam propagation in a medium that has nonlinear refraction and absorption. Moreover, a numerical algorithm is developed for solving the NPWE in a medium with arbitrary thickness and nonlinearity. Through the Huygens-Fresnel principle, the intensity distribution behind behind the sample is determined, thereby completing the general Z-scan theory.
